Application filed June 6, 1910. Serial No. 565,229.

To all whom it may concern:

Be it known that I, HENRY M. TILESToN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Axles for Vehicle-VVheels, of which the following is a full, clear, and exactspecification.

This invention relates more particularly to that type of axlesforvehicles in which the axle spindle is separate from the axletree, andhas pivotal relation thereto so that the spindle may rotate on avertical axle to facilitate the steering of the vehicle, although insome instances this invention is applicable to separate spindles whichdo not have this pivotal or rotary movement with relation to theaxletree.

The invention has for its primary object to provide an improved axle forvehicles, in which the axle spindle will be yieldingly held in positionwith relation to the axletree, so as to relieve the axletree of severeor sudden shock or jar, thus enabling the wheels at the fore ends of theaxles to rise and fall without lifting the entire vehicle. Anotherobject of the invention is to provide an improved axle for vehicles inwhich the spindle will be pivotally related to the axletree and alsoyieldingly supported thereon so as to be capable of vertical movementwith relation thereto.

VVit'h these ends in view the invention consists in certain features ofnovelty in the construction, combination and arrangement of parts bywhich the said objects and certain other objects hereinafter appearing,are

attained, all as fully described with reference to the accompanyingdrawings, and more particularly pointed out in the claims.

In the said drawings-Figure 1 is a vertical sectionalview of one end ofan axle constructed in accordance with this invention. Fig. 2 is atransverse section on the line 22 of Fig. 1. Fig. 3 is a View similar toFig. 1, illustrating certain modifications hereinafter described. Fig. 4is a transverse section thereof taken on the line 44 Fig. 3.

1 is the axletree, and in this exemplification of the invention is shownas being of the type having a yoke 2 secured to or formed on one end andprovided with laterally projecting arms 3. These arms 3 are similar tothe arms or lugs ordinarily employed on axles of this type used forautomobile structures, and between which arms or lugs the rotarystandard of the axle spindle is usually pivoted.

4 is the axle spindle, which in this form of the invention is formed onor secured to a slide 5, which, as better shown in Fig. 2, is square orangular in cross section, and is held and guided in a box 6, which isconsiderably longer than the slide 5, so that the ends of the slide willhave room to rise and fall in the box 6. The front or outer side of thisbox is cut away as shown at 6, to leave room for the up and down motionof the spindle 4, and interposed-in the ends of the box at both ends ofthe slide 5 are cushions, preferably in the form of elastic balls 7. 8,and these, if desired. may be hollow and filled with air. The box 6 ispivoted by any suitable means, such as by studs 9, between the arms 3.so that it is capable of rotating on a vertical axis, while the slide 5with the spindle 4, will be free to rise and fall vertically, thusadapting the device for the steering wheels of an automobile or thelike. and at the same time yieldingly supporting the axle spindle so asto relieve the axletroe of the sudden jar orshock to which the wheel issubjected during Ordinary usage.

When the device is used for the steering wheel of an automobile or thelike, the box 6 may be provided with the usual arm 10, and this isconnected to the steering mechanism 11 by means of a suitable joint 12,as usual, the element 11 in this instance being a cross-rod whichconnects the arm 10 of one of the boxes 6 at one end of the axle withthat at the other end, the slide 5 and interior of the boxes beingsquare or angular, it is ofcourse understood that the slide is free toreciprocate within the box, but is not free to rotate independentlythereof, and consequently must obey the control of the arm 10.

In the modification shown in Fig. 3, the box in which the slide of thespindle 4 is mounted is formed on and is a part of the yoke 3. It willbe seen that the arms 3 of this yoke are formed with cups 13, whichproject toward one another and these are provided with axial extensionsl-i similarly arranged, but detachable therefrom so as to facilitate theintroduction of the slide which in this form is shown at 5. The joints15 which connect the extensions 14 to the cups 13 are located just aboveand below the ends of the slide 5, so that when these extensions 14 areunscrewed and slipped one upwardly 5 and the other downwardly on theslide, the

jure the balls 7, 8, anti-friction washers 16 may, if desired, beinterposed between the ends of the slide and the balls.

With an axle thus constructed 'it will be appreciated that the shock andjar caused by the Wheels encountering obstructionsor irregularities onthe road way, .will be as effectually absorbed or relieved as is nowaccomplished by means of the pneumatic tire. What I claim is: v

1. In a device of the class described, the combination with a vehicleyoke, of alined bearing cups oppositely disposed, resilient bearingmembers in the'cups, axial extensions for the cups, and an axle spindleformed on a slidable member mounted and slidable in the said extensions.

2. In a device of the class described, the

sitely disposed and alined bearing cups, ex-

tension shells removably secured to said cups, resilient bearing membersin the cups,

' and a rotatable member slidably mounted in said shells and bearingupon said bearing members, said slidable member being formed with alaterally projecting axle and means to rotate the member in the shells.

4:. In a device of the class described, the combination with a yokeformed with'spaced bearing cups, extension shells removably secured tothe cups, resilient bearing members in the cups, and a member rotatablymounted in the shells having bearing engagement with said bearingmembers and of a length less than the spaced distance of said cups.

In testimony whereof I have signed my name to this specification, in theresence of two subscribing witnesses, on this 3rd day of June A. D.1910.
